Create your Jelastic Environment

3.The Environment Topology dialog box will be opened. To start with, choose your programming language by clicking on the appropriate tab in the upper part of the dialog box:

4.Here you can fully customize your environment settings.

Now let’s consider each of the available blocks in more details:

Balancing

Application Servers

– Type and version of application server

– Engine version

– High Availability

– Public IP

Memcached

Databases

– SQL Database

– NoSQL Database

Additional Options

– VPS

– Build node

– SSL

Docker

Summary List

Balancing

If you want to set up the load balancing, simply pick the NGINX-balancer node by clicking the Balancing button (also, it is automatically enabled if you use more than one server). Then, specify the resources limits for vertical scaling of your server (fixed and dynamic amount of cloudlets you want to use) in the center section of the Environment topology window.

If you need an external IP address, switch on the Public IPv4 option (please note: this is a paid add-on).

Application Servers

Click the Application servers button.

In the first drop-down menu choose the application server you want to use (GlassFish 3.1, Jetty 6.1, TomEE 1.7, Tomcat 6/7, Apache 2.2, NGINX 1.6, Node.js 0.1, IIS 8 or any other one available by means of cartridge).

You can change the cloudlet limits per server (vertical scaling) using the sliders (for fixed and dynamic amount of cloudlets separately).

Use the +/- buttons between the application server icons to scale your server horizontally (more or less nodes).

In the second drop-down menu choose the desired Engine version:

Java versions – Java 6, Java 7 or Java 8;

PHP versions – PHP 5.3, PHP 5.4, PHP 5.5 or PHP 5.6;

Ruby versions – Ruby 1.9.3, Ruby 2.0.0, Ruby 2.1 or Ruby 2.2;

Python versions – Python 2.7, Python 3.3 or Python 3.4;

In case of NodeJS or .NET usage, the only available version (Node.js 0.10 or .NET 4 correspondingly) will be chosen automatically.

If you need it, you can switch the High Availability on for your Java or .NET application server. You can also attach the Public IPv4 address to your app server, regardless of the used programming language (please note: this is a paid add-on).

Memcached

Using the Cache icon, you can add a Memcached node.

Use the sliders to change the cloudlet limits for its vertical scaling.

Databases

There are two sets of databases available: SQL and NoSQL databases.

Click on the SQL icon to activate an SQL Database. You can choose your database from the drop-down list: MariaDB 5.5, MariaDB 10.0, MySQL, PostgreSQL 8.4, PostgreSQL 9.4, MSSQL 2012 (or any other available by means of cartridge).

Then specify the cloudlet limits using the sliders. If you need it, switch on the Public IPv4 (please note: this is a paid add-on).

Click on the NoSQL icon to activate a NoSQL Database. Choose your desired database from the drop-down menu.

Then specify the cloudlet limits using the sliders. If you need a public IP, switch on the Public IPv4 option (please note: this is a paid add-on).

Additional Options

There are a few additional options available: VPS, Maven and SSL.

If you want to use an Elastic Virtual Private Server (VPS), click on the same-named VPS icon, choose the required one via the appeared drop-down list (Centos 6.6, Windows 2012 or Windows 2008) and scale it vertically by changing the cloudlet limits.

Note: that VPS containers are provided with the automatically attached external IP address by default.

To use a Maven build-node (for Java projects), click the Build icon and specify the cloudlet limits for its vertical scaling using the sliders.

If you want to activate an SSL for your environment, click on the corresponding icon at the top part of the wizard frame (above topology blocks).

Jelastic gives you an opportunity to choose between Jelastic SSL (only application server is required) and Custom SSL(application server/NGINX balancer with Public IP is required).

Docker

In addition to the variety of available programming languages, the environment wizard contains one more special Docker tab, intended for creation of containers, based on Docker templates. Inside, you’ll find four equal blocks with different layer names to the left, where you can select any amount of Docker containers with required software (added either within just one section or to different ones).

Once a particular template’s slot is chosen (at the bottom part of the frame), you can specify the resources limits for it using the cloudlets sliders, attach the Public IPv4 address (please note: this is a paid option) or perform some basic container configurations through a separate graphic tool (Edit button).

Also, the above-mentioned SSL option is available for Docker-based environments (currently only the Jelastic SSL certificates are supported).

Summary List

On the far right of the wizard, in the Resources (cloudlets) pane you will see the overall amount of selected cloudlets for all nodes in your environment, your discount, and approximate Total monthly cost.

Use the Cost details and Quotas & Pricing links for getting more detailed information on resources consumption and price.

Finally, type a name for your environment and click the Create button. Your environments will be listed in the upper pane of the admin panel alongside the information about its status, deployed files and resources usage.
